Dear Mr. Keppler:

Operating License DPR-58 Docket No. 50-315 This letter is to confirm our verbal report to NRC Inspector, K.R. Baker, on June 17, 1976.

On June 16,

1976, Mr. Baker was reviewing Instrument Maintenance Procedure data and determined that we had violated Appendix A Technical Specification Section 2.2.

1 and Table 2.2-1 Item 9.

Due to procedural error the correction for the static pressure leg was improperly applied in the calibration of the pressurizer pressure transmitters.

The error had been found ar.'. corrected on April 12, 1976, but had not been reported to the NRC.

Plant Nuclear Safety Review Committee review of this incident on June 17, 1976, revealed that we had a1so violated Appendix A Technical Specification Sections 3.3.2. 1, Table 3.3-4 Item ld and 3..2.5.

The PNSRC's analysis of this error indicates that the health and safety of the public was not in jeopardy.

Our investigation is continuing and a formal report wi 11 be submitted as required by HRC Regulatory Guide 1.16, Revision 4, by July 1, 1976.

Sincerely, R.W. Ju nse Plant Manager
